Biography

C.W. Yu received his M.Sc. in Electrical Power System from the University of Manchester Institute of Science and Technology, UK and his Ph.D. from the Hong Kong Polytechnic University in 1976 and 1998, respectively. From 1977 to 1979 he worked in the power system protection department of the China Light & Power Co. From 1979 to 1980 he worked in the power supply department of the Mass Transit Railway Corporation. He joined the Hong Kong Polytechnic (former The Hong Kong Polytechnic University) in November 1980 and was an Adjunct Associate Professor in 2018.  He is currently a Senior Lecturer with the School of Professional Education and Executive Development, The Hong Kong Polytechnic University. His research interests are in power system economics, restructuring of the electricity supply industry, open electricity power market operation, transmission and ancillary services pricing development and implementation.
